Sets the percentage threshold of Java heap memory usage that triggers
LowMemoryExceptions on a GemFire XD data store. This procedure executes
only on the local GemFire XD data store member.
This procedure sets the percentage
threshold of critical Java heap memory usage on the local GemFire XD data store. If the
amount of heap memory being used exceeds the percentage, the member will report
LowMemoryExceptions during local or client put operations into heap tables. The member
will also inform other members in the distributed system that it has reached the
critical threshold. When a data store is started with the -heap-size
option, the default critical threshold is 90%.
IN PERCENTAGE REAL NOT NULL
- The percentage of used heap space that triggers
LowMemoryExceptions on the local GemFire XD data store.
This command sets the critical threshold for heap memory usage on the local GemFire
XD member to 99.9%:
call sys.set_critical_heap_percentage (99.9);
